This lecture describes WiFi models via an example of QoS over IEEE 802.11 network. First we will give an overview of 802.11 protocol. Then a model proposed by Bianchi [1] will be presented to compute the packet delay of 802.11 DCF (Distributed Coordination Function). We extend this model to 802.11e EDCF (Extended Distributed Coordination Function) to study the QoS for voice it can provide. I. O...

Advanced Trauma Life Support (ATLS) courses teach a system for the initial assessment and management of trauma patients that aims to optimise initial care and reduce mortality and morbidity, and have been adopted worldwide. This questionnaire survey characterised those who took up this particular educational resource in Scotland during a four year period after its introduction, and analysed how...

Occludin is a tetraspan integral membrane protein in epithelial and endothelial tight junction (TJ) structures that is projected to have two extracellular loops. We have used peptides emulating central regions of human occludin's first and second loops, termed O-A:101-121 and O-B:210-228, respectively, to examine potential molecular interactions between these two regions of occludin and other T...

The Naturally Occurring Radioactive Materials (NORMs) that are potentially generated from oil and gas extractions in Albania have been disposed of without regulations for many decades, and therefore, an extensive survey in one of the most productive regions (Vlora-Elbasan) was performed. A total of 52 gamma ray spectrometry measurements of soil, oil-sand, sludge, produced water and crude oil sa...
